SPECIFICATION forming part of Letters Patent N 0. 600,449, dated March8, 1898.

Application filed November 3, 1897. Serial No. 657,244. (No model.)

To aZZ whom it may concern:

Be it known that I, ALoNzo FRANK RIoH- ARDSON, a citizen of the UnitedStates, and a resident of New York, in the county of New York and Stateof New York, have invented certain new and useful Improvements in NasalInjectors; and I do hereby declare that the following is a full, clear,and exact de' scription of the invention, which will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, which form a part ofthis specification.

My invention relates to nasal injectors for containing medicines orremedies for the cure of catarrh, which are injected into the nostrilsby pressure upon the tube, which tube is made of metal foil, after themanner of paint-tubes for holding artists colors. The object of theinvention is to provide an improved nozzle or point for such nasalinjectors which shall possess superior advantages with respect toefficiency in use.

The invention consists,essentially,in a tube of metal foil with a diskof more rigid metal at the upper end, a lengthened nozzle securedthereto, screw-threaded at the base and reduced and plain from saidscrew-threaded portion to the point, so as to be extended well up intothe nostril, a rubber or other elastic disk connected with said tubeintermediate its ends, and the cap screw-threaded at one end to engagewith the screw-threads of said nozzle, as hereinafter fully describedand claimed.

In the accompanying drawings, Figure 1 is an elevation of a nasalinjector constructed in accordance with my invention, the cap beingremoved and shown at one side thereof. Fig. 2 is a vertical section ofthe same.

In the said drawings the reference-numeral 1 designates a tube of thinmetal or foil capable of being easily compressed by the fingers, so asto expel the contents. The up per end of this tube is secured to a diskof thicker metal, so as to be comparatively rigid.

Secured to this disk is a nozzle 2, with an enlarged and screw-threadedbase or inner end 3, the remaining portion 4 being made plain andtapering. This tapering portion of the nozzle is of a length sufficientto extend well up into the nostrils, and intermediate its end is formedwith a peripheral groove 5, with which engages a rubber or other elasticdisk 6 for preventing the point of the nozzle from coming in contactwith the nostrils and thereby injuring the same.

The numeral 7 designates a cap corresponding in shape with the nozzleand screwthreaded to engage with the screw-threaded base 3.

In practice the cap is removed and the nozzle inserted in the nostril.The tube is then pressed between the fingers and thumb,which will expelthe medicine contained therein and inject it into the nostril.

Having thus fully described my invention, what I claim is- 1. In a nasalinjector, the combination with the compressible tube of metal foil andthe tapering nozzle formed with a peripheral groove intermediate itsends, of the elastic disk fitting over said nozzle and engaging withsaid groove, substantially as described.

2. In a nasal injector, the combination with the compressible tube ofmetal foil, the rigid metal disk at the upperend thereof, the taperin gnozzle formed with an enlarged screwthreaded base secured to said diskand said nozzle intermediate its ends formed with a peripheral groove,of the elastic disk engaging with said groove and the screw-threaded capfitting over said nozzle and engaging with the base thereof,substantially as described.

In testimony that I claim the foregoing as my own I have hereuntoaifixed my signature in presence of two witnesses.

ALONZO FRANK RICHARDSON.
